Area Forecast Discussion National Weather Service Wilmington NC 303 AM EDT Wed Jul 15 2020

SYNOPSIS. A dome of above average warmth will cover the Carolinas through the week, maintaining hot and humid weather along with only isolated showers or a thunderstorm. Storm coverage will increase over the weekend and early next week, as an upper ridge over the region starts to weaken.

NEAR TERM /THROUGH THURSDAY/. Isolated convection across the Darlington area has dissipated with debris clouds lingering across the far western zones. In addition, debris clouds from storms in MHX's area are also fanning southward across the northeast zones. As a result the range in sky character varies from SKC to mostly cloudy early this morning. The mid/upper ridge will persist across the Carolinas today but will slowly migrate westward during Thursday. This feature along with only marginal instability will act to limit the areal extent of convection which will mainly be diurnally driven with the sea breeze providing some lift today and Thursday. While it will be hot with highs in the lower 90s inland to the upper 80s at the coast the heat index will not be as high as in the past couple days. Low temperatures tonight will only be slightly above normal.

SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/. Mid level ridging will be firmly in place with Bermuda High Pressure and the inland trough at the surface. Chances of convection remain at or below climatology at least for now. High temperatures will be in the lower 90s with slightly cooler readings along the coast. Lows will be in the lower to middle 70s.

LONG TERM /SATURDAY THROUGH TUESDAY/. The ridge across the area seems to want to break down and or move to the west in time allowing for better chances of convection. The highest pops occur Monday and Tuesday as there appears to be better mid level support with jet dynamics. Temperatures will hover around or just above climatology driven somewhat by convection and debris.

AVIATION /07Z WEDNESDAY THROUGH SUNDAY/. VFR conditions expected through the TAF period at all terminals. Primarily SKC initially all locations expect KFLO with convective debris from dissipating -SHRA a county away. Isolated to widely scattered -SHRA/-TSRA possible with daytime heating and the sea breeze as a possible trigger this afternoon. No enough coverage expected to include at the terminals at this time. Sea breeze circulation will allow winds to turn onshore an increase a notch at the coastal terminals this afternoon.

Extended Outlook . Convection may increase into the weekend as the ridge aloft weakens, this will lead to higher chances of brief MVFR/IFR, induced by nearby storms.

MARINE. A weak ridge of high pressure will build across the coastal waters from the north today allowing for light easterly flow. Speeds will increase a notch during Thursday as the pressure gradient tightens some and as the sea breeze adds to the onshore flow. Overall, seas of 2 to 3 ft will be the rule , but closer to 3 ft during Thursday.

A very modest southeast flow will be in place Friday into Saturday with wind speeds outside of the sea breeze area ten knots or less. The flow will become more south and southwest for the remainder of the period with similar wind speeds. Significant seas are very stable at two feet or so with a mix of a lower period wind wave and slight swell component.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
